Answer;
-23 in males
In humans, 23 in males is the only homologous chromosome pair that isn't the same.
Explanation;
-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.
The alignment of the earth, moon, and sun during a solar eclipse is Sun, Earth, moon.
Answer:
1.fungi, 2.fungi 3.monera 4.fungi 5. protista 6. animalia
Explanation:
since, yeast is a fungus , penicilium and mushroom (agaricus) also fall under this catergory due to the <em>presence of mysceliom and hyphae.</em>
rizobium is a <em>bacteria</em> so falls under the kingdom monera
amoeba has <em>locamotory organs</em> hence is a part of the protista kingdom
while , fish is <em>an animal</em> and thus belong to animalia
Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are <em>EcoRI</em>, <em>BamHI</em> and <em>HindIII</em>, isolated from <em>Escherichia coli</em>, <em>Bacillus amyloliquefaciens</em> and <em>Haemophilus influenza</em>, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.
Answer: The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space The atmosphere keeps the average temperature of the Earth fairly steady during the day and even during the course of the whole year.
